[bug\_fix] standard\_init\_linux.go:228: exec user process caused: exec format error

Ensure the binary or script executed by ENTRYPOINT/CMD matches the container's target architecture. When building on ARM \(e.g., Apple Silicon\) for AMD64 targets, use \`docker build --platform linux/amd64\` or \`FROM --platform=linux/amd64\` to compile/run the correct architecture binaries.

Journey Context:
A developer builds a Docker image on an Apple Silicon \(ARM64\) Mac and pushes it to a registry. Their CI/CD pipeline pulls the image onto an AMD64 Linux runner, and the container immediately crashes with 'exec format error'. The developer spends hours checking file permissions, shell script line endings \(CRLF vs LF\), and entrypoint paths, all of which are correct. They finally realize the image was built natively as ARM64, and the AMD64 host cannot execute the ARM64 ELF binary. By rebuilding with \`--platform linux/amd64\`, Docker uses QEMU to emulate AMD64, producing a compatible binary that runs flawlessly on the CI runner.
